Capital Foundation & Waterproofing Ltd. can provide structural repairs to your foundation.
Before deciding on a repair method, we examine moldings, trim boards and mortar joints to determine whether your foundation will require structural repairs. We provide three main structural repair services in Ottawa:
If your foundation is sinking, it was likely installed on poorly-compacted dirt, which has begun sinking with the weight of the foundation on top of it. Jacking corrects a slab's position and prevents you from having to replace the whole concrete slab. Instead, we simply float the slab back to its original position by pumping additives beneath the slab. This method causes little or no disruption to landscaping, nothing needs to be moved off the slab, and it typically costs half as much as replacing a slab.
Foundation underpinning is the process of strengthening the existing foundation by extending its depth so it rests on more supportive soil, or its load is distributed across a broader area. A building typically needs underpinning when cracks are wider than ¼ inch, and there are signs of a faulty foundation. The most common underpinning method is the mass pour method, where sections are excavated in sequence to a pre-established depth below the footing, and extra concrete is placed in each pit.
Foundation Wall Replacement
Sometimes a repair isn't sufficient to solve your foundation problem. You may have significant damage to your walls. You may also have old walls that were built with inferior materials and methods, and they now lack the structural integrity needed to hold your house up. If your walls are deteriorating, we usually recommend replacement. We ensure each wall replacement project goes smoothly and quickly to minimize disruption to your home. The process includes:
Building a temporary framework to support the beams and floor joists that are held up by the wall that needs to be replaced
Removing soil from around the foundation
Dismantling the old wall and footings (if your foundation has footings)
Putting up the new wall, tying each course of concrete blocks into existing adjacent walls
Dismantling the temporary supports
